Hi all. I need some help as my system is totally dead after trying to update my system with the update manager UI tool. After the update and the reboot, I got the error message “Failed to start Load Kernel Modules”, a bunch of “Failed to Mount unit for core” and some other stuff. BTW, during the update the update manager complained about some nVidia drivers - don’t know if this is important.
I tried following the steps for other similar issues and now I have a new screen when I boot:
Warning: /lib/modules/5.10.2.-2-MANJARO/modules.devname not found - ignoring
mount: /new_root: unknown filesystem type ‘ext4’
You are not being dropped into an emergency shell.
sh: can’t access tty: job control turned off
[rootfs ]#
The root prompt is totally unresponsive.
From the livecd, lsblk give the following. sda is my boot drive (or was my boot drive)
[manjaro@manjaro ~]$ lsblk

Sorry but with vague description like this you very unlikely will get any help. Please learn how to write support request posts, include logs, learn how to debug your system. Restore from backup.
@cryptocurious, sorry this wasn’t complete enough , so here is everything on the boot screen at the time of the original failure.
[FAILED] Failed to start Load Kernel Modules.

At this point, the system was stopped and could only be reset, so I reset it and rebooted to a live image via USB. I then came to the forums and found other issues with the same failure. I follow the steps in those tickets and now when I boot I get this screen:
Warning: /lib/modules/5.10.2.-2-MANJARO/modules.devname not found - ignoring
mount: /new_root: unknown filesystem type ‘ext4’

The system is totally unresponsive, meaning it accepts no keyboard input of any kind and can only be rebooted. This is the current state of my system. I have decided to ask for help at this point to prevent making matters worse.
@Keruskerfuerst, I will look to see if I can get GRUB to come up and if there is another boot option but right now I am seeing no option to boot into anything.
@Keruskerfuerst,
I was able to boot into another kernel, 5.9.16-1, linux59.
I have 3 versions installed, 5.10.2-2 and 5.4.85-1. I assume 5.10.2-2 is my corrupted image and my plan of action is to remove it and fall back to linux59. Is this the right path to take?
I did not specifically install linux510 or linux59 and I am probably quite happy with linux54. I suspect these versions arrived as part of pamac updates. When pamac says there are updates, I have been treating these as things I need to do for security, stability, etc. reasons and so I update. Should I not be doing this?
